Resting Metabolic Rate and Social Status in Juvenile Giant Freshwater Prawns, Macrobrachium rosenbergii

摘要: Forty post-larval giant freshwater prawns (Macrobrachium rosenbergii) were weighed, measured, marked and placed in groups of 4. Social interactions screened daily, moults recorded the nature stability dominance characterised. Half for resting oxygen consumption before group formation. In most groups, one or two individuals ('dominants') consistently won majority which they involved, while others ('subordinates') lost; remainder classified as intermediate social status. Prawns lost more fights on day a moult, but despite this, rank was retained after moults. Neither initial size nor growth rates varied with status, that became dominant had significantly higher metabolic formation than those subordinate. Thus M. rosenbergii outcome aggressive can be predicted from physiology animals although...
